As a resident of Horley, without a swimming pool, I remember well the familiar rattle of G-LINK in and out of Gatwick. And if you were on the spectator's terrace at Gatwick you would be treated to the sight of it heading straight for you from the West, then banking at the last moment and landing in front of the terminal. Occasionally other S-61s would be substituted, but G-LINK was the key machine used. A few pictures can be found on my website:

Whatever the background of the operator, the markings were always British Caledonian blue and yellow/gold.
